Looking for tiny screws

[SAMyMAS]

Hello All,

I am looking for the following screws in gold colour,

Dimensions in millimetres
Head diameter
0.83 - 0.84
Thread Size
0.47 - 0.48
Length
1.57 - 1.58

I’m thinking of these ones Diagram 101 and 127

cousinsuk.com/product/bridge-screws-wristwatch-graded#

cousinsuk.com/product/balance-screws-wristwatch-graded

But I can’t find their thread and length other than reference to ‘diagram’

I would appreciate if someone advise/point me finding/buying them.

Thanks

What movement is it for and what part are they for?

Thank you @AndyGSi for following up.

I don’t know the movement. They are from Chopard ‘happy diamonds’ battery clasp/clamp.

Being a battery clamp the screws you're looking at on Cousins won't work.

There should be a number somewhere on the movement and photos would help.

Hi need pictures of the movement and calibre number .

[SAMyMAS]

Movement 

ETA 201.001

 

Calibre

9.9mm

 

SCREW, CELL CLAMP # 

X/12142 (54400/201.001) 

 

I found these two suppliers so far,

https://hovigs.com/products/battery-clamp-screw-x-12142

 

The estimate total cost for 5pcs is ~ €70 including shipping import tax EU

 

I would rather buy within Europe to cut shipping/tax expenses. Cousinsuk indicates it’s discontinued.

I would get a couple of these selections first, good chance of finding something to fit

The part you've shown is a Ronda 726 screw. If you've searched 54400 then that's just the generic part no. for battery clamp screws.

The 51.600.01 is used across multiple ETA movements. (example 210.001)

 

 

[SAMyMAS]

Splendid. Yes I have searched for the part, instead of the movement. Thank you again @AndyGSi

Thank you @tomh207 for the advice. I will take them too. They might be handy in the future.

Have a good day.

I have checked part numbers in ‘Swiss part description’. Am I right assuming they are interchangeable to the subject one - same dimensions and colour?

If that’s so, than I found better price for ~£2.

[tomh207]

That’s how I read those, similar prices per screw as well so I would go with the 3 pack and have a spare

[AndyGSi]

The ISA one is a completely different screw for the ISA 369 movement.

[SAMyMAS]

Thank you Tom for the confirmation. I will go for 3 pack. Thank you Andy for the wise observation. I learn now that the movement/calibre ought match part number.

As mentioned earlier, sometimes the calibre can be different as a lot of parts are
used across them but the key part is the manufacturer which in your case is ETA.

Hello Samy i hope everything is well on your end. I too am looking for the same exact screw that I saw you posted about me too for a chopard watch. Could you please let me know if you were succesful in finding one where you ordered it from and how fast the delivery was. Any advice or help in this matter is welcome. Thank you so much for your help

[SAMyMAS]

Hello @Tahagg

The identical screw is: SKU X/12142, 0 54400 / 201.001

I bought similar ones from cousins.uk: ETA21000154400, ETA 210.001 54400 as kindly suggested by @AndyGSi, but notice they are silver colour not yellow/golden, other than that I think they should fit, but I didn’t try. The delivery in EU is within 10 days.

I bought the identical screws - yellow/golden from US, hovigs.com *****@*****.tld. They’re are very nice to deal with.
